Efficient flexible perovskite solar cells and modules were developed using a combination of SnO2 and mesoporous-TiO2 as a fully solution-processed electron transport layer （ETL）. Cells using such ETLs delivered a maximum power conversion efficiency （PCE） of 14.8%, which was 30% higher than the PCE of cells with only SnO2 as the ETL. The presence of a mesoporous TiO2 scaffold layer over SnO2 led to higher rectification ratios, lower series resistances, and higher shunt resistances. The cells were also evaluated under 200 and 400 lx artificial indoor illumination and found to deliver maximum power densities of 9.77 μW/cm^2 （estimated PCE of 12.8%） and 19.2 μW/cm^2 （estimated PCE of 13.3%）, respectively, representing the highest values among flexible photovoltaic technologies reported so far. Furthermore, for the first time, a fully laser-patterned flexible perovskite module was fabricated using a complete three-step laser scribing procedure （P1, P2, P3） with a PCE of 8.8% over an active area of 12 cm^2 under an illumination of 1 sun.

Late-onset hypogonadism： beyond testosterone

引用

Asian Journal of Andrology 2015年第2期17卷 236-238,I0008页

作者： carlo Foresta aldo E Calogero Francesco Lombardo Andrea Lenzi Alberto Ferlin Department of Medicine and Centre for Human Reproduction Pathology University of Padova Padova 35128 Italy Department of Medical and Pediatric Sciences Section of Endocrinology Andrology and Internal Medicine University of Catania Catania 95123 Italy Department of Experimental Medicine Section of Medical Pathophysiology and Endocrinology Sapienza University of Rome Rome 00185 Italy

Late-onset hypogonadism is defined as a combination of low testosterone （T） levels and typical symptoms and signs. A major area of uncertainty is whether T concentrations are always really sufficient to fully reflect Leydig cell （dys）function. Mild testicular alteration could be diagnosed only by additional biochemical markers, such as luteinizing hormone （LH） and 25-hydroxyvitamin D levels. These markers help in identifying the so-called ＂subclinical＂ hypogonadism （normal T, high LH levels）. Patients with hypogonadism have frequently low levels of 25-hydroxyvitamin D due to impairment of the hydroxylating enzyme CYP2R1 in the testis. However, no data have been published dealing with the best treatment option （cholecalciferol - the Vitamin D precursor, or calcidiol - 25-hydroxylated form of Vitamin D） in these patients. We studied 66 patients with classic hypogonadism （total T [TT] 〈12 nmol I-~, LH 〉 8 IU 1-1）（n = 26） and subclinical hypogonadism （TT 〉 12 nmol I-＊, LH 〉 8 IU I-~）（n = 40） and low 25-hydroxyvitamin D （〈50 nmol I-1）. Subjects received cholecalciferol （5000 IU per week）（n = 20） or calcidiol （4000 IU per week）（n -- 46）, and 25-hydroxyvitamin D and parathyroid hormone （PTH） were evaluated after 3 months of therapy. Supplementation with calcidiol significantly increased 25-hydroxyvitamin D and significantly decreased PI＂H levels in both groups of men with hypogonadism （primary, n = 16 and subclinical, n = 30）, whereas supplementation with cholecalciferol did not modify their levels. This study shows for the first time that the administration of the 25-hydroxylated form of Vitamin D （calcidiol）, and not the administration of the precursor cholecalciferol, restores 25-hydroxyvitamin D levels in subjects with hypogonadism.
